InvalidDeploymentException indicates the existence of a corrupt deployment or application manifest in a ClickOnce application. The error might occur because the manifests are poorly formed, have unrecognized elements for their schemas, or have mismatched digital signatures.

You are more likely to have corruption if you manually edit the deployment or application manifest files with a text editor. You can usually correct this problem by regenerating your ClickOnce deployment, which will create new deployment and application manifests. For more detailed debugging steps, see the following links.
